[BUG] yaml file time requires quotation marks

[jlmaurer]

Describe the bug
Time requires quotation marks to work properly, most likely due to a version change in how the yaml parser handles numbers in the yaml file.

To Reproduce
Steps to reproduce the behavior:
List time as 00:00:00 in yaml file
Using "00:00:00" works

Expected behavior
Should not need to specify the quotes, just need to handle the integer case in enforce_time
